COPY

 

Description: This function generates a new set of unreferenced nodes at a user-specified location from either referenced or unreferenced nodes.

 

Usage:

 

1.   DSI prompts:

>   SELECT NODES

•    Once the nodes have been selected, DONE concludes this step.

 

2.   DSI prompts:

>   CREATE LOCAL COORDINATES

>   PICK NODE/PT FOR ORIGIN

 DSI prompts the user to create a local coordinate system.  A thorough explanation of how to create a local coordinate system is covered in Local Coordinate System, Section 2.16.

 

3.   Once the desired coordinate system is acquired, it will be displayed on the screen and the prompt will read:

>   ACCEPT? (Y/N/A)

•  If YES, the user goes to step 4.  If NO, the user returns to step 2. If ABORT, the user exits the function COPY and returns to the NODE OPTIONS menu.

 

4.   If the user selects YES, DSI prompts for the number of copies and the type of transformation:

>   ENTER NUMBER OF COPIES (positive integer)

>   MOVE OR ROTATE (M/R)

    

 

?   MOVE

>   ENTER U, V, W INCREMENTS

•    e.g. 0,0,1000.  This entry will copy the selected node(s) 1000 units along the W-axis.

ROTATE

>   ENTER ANGLE INCREMENT

•    Enter the angle increment (right hand rule) for local W or global Z.
